Summary

B7-H3 is expressed at low levels in normal tissues but overexpressed in various tumor tissues. The ubiquitous expression of B7-H3 in tumors of different grades is a key feature for brain gliomas. The immunohistochemistry study showed that B7-H3 is abundantly expressed on both glioma (especially high-grade glioma) cells and tumor-associated endothelial cells. For GBM, the expression of B7-H3 is intensely positive, especially on tumor cells and vascular endothelial cells, which makes B7-H3 a potential immunotherapeutic target.

γδ T cells recognize tumor cells without being restricted by MHC molecules, and thus can be used in allogeneic therapy without the risk of causing graft-versus-host disease.

This study is an open-label, single-arm, dose-escalation and dose-expansion clinical study aimed at evaluating the safety and efficacy of allogeneic B7-H3 CAR γδT in patients with malignant glioma.

Conditions

  • Brain Gliomas
  • High-Grade Gliomas
  • GBM

Interventions

BIOLOGICAL

Allogenic B7-H3 CAR-γδT cell(QH104)

Dose escalation (3+3) : dose 1 (1 × 10\^7 CAR+cells) , dose 2 (3 × 10\^7 CAR+cells), dose 3 (6× 10\^7 CAR+cells), once every 4 weeks via an Ommaya reservoir or intrathecal administration. Dose expansion 1: dose of RP2D, once every 4 weeks via an Ommaya reservoir or intrathecal administration. Dose expansion 2: 3 × 10\^7 CAR+cells, every two weeks for three consecutive months, then changed to once every 4 weeks via an Ommaya reservoir or intrathecal administration.
